Be it known that I,V WILLIAM WESTLAKE, of the city of Brooklyn, in the county of Kings, and State of New York, have invented a certain new and useful Improvement inl Lantern-Globes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had tothe accompanying drawings, making a part of this specification, the figure shown being a full view.

The nature and object of' my invention consist in constructing a lantern-globe of different colors in a single piece.

Heretofore lanterns have been made to show dilferent colors by using separate pieces of colored glass or colored rings around the burner inside of the globe; and 'all of these arrangements have been found to be exceedingly liable to disorder or breakage, or both.

For the use of conductors of railway-trains, and for other purposes, it is desirable to have diiferent colors shown, and by this arrangementiof colors all ofthe purposes of a signal-lantern are subserved, while the light from below is unobstructed by the coloring of the glass or the shading of separate pieces, so that a conductor can collect his fares or tickets with as clear a light as is shownby an uncolored globe or light, and the light thrown upon the floor or upon the ground is not interfered with, so that the lantern is not injured for general purposes, and is equal to any as a signal-lantern. A

To enable others skilled inthe art to make and use my improved globe, I will describe its construction and operation. i

The base, A B C', mountings D, bail E, and guards F, may be made in the form shown, or in any of the forms known or used in the construction of lanterns. The globe G II is made with its upper part, II, colored, and-its lower part, G, clear or uneolored, as shown, and the colored portion is brought down so as to come on a line, or nearly on a line, with the top of the flame; a little distance above or below, however, is not material. These globesare made in two ways or modes. By one mode the globe is blown or made clear, and a separate ring made to fit over it, and stained in the glass' by any of the usual modes, and then put over the globe, and annealed, so as to adhere to the globe and form a part of it. The other modeis to make them originally in two parts,`thc upper portion, H, stained, and the lower portion, G, clear, and anne-al them together so as to form a single globe. I preferthe latter method, as it makes a more regular and perfect line between the colored or stained portion and the clear portion than the other-mode, and leaves the globe of equal thickness throughout its entire length, and a deeper tint or color can he given, unless the globe in the other process of manufacture is lined both on the outside and inside. The seam or line of junction may be vertical, so as to give the lantern two fronts. y

Its operation will readily he seen from thel drawings, and understood without description, as it will` be seen that the horizontal rays of light, and those below the plane ofthe flame, will be clear, while those above will be colored, and the colored portion can be seen and distinguished ata great distance.

What I claim as new, and desire to secure by Letters Patent, is-

A lantern-globe, made of or finished into a single piece, having one portion colored and a part clear, substantially as specified.
